[PATCH v3 0/2] docs: Integrate rustdoc into Rust documentation

[Carlos Bilbao <carlos.bilbao@amd.com>]

Include HTML output generated with rustdoc into the Linux kernel
documentation on Rust.

Carlos Bilbao:
 docs: Move rustdoc output, cross-reference it
 docs: Integrate rustdoc generation into htmldocs

---

Changes since V2:
 - Split v2 into two-patch series.
 - Add "only:: html" directive in Documentation/rust/index.rst reference

Changes since V1:
 - Work on top of v6.1-rc1.
 - Don't use rustdoc.rst, instead add link to Documentation/rust/index.rst.
 - In Documentation/Makefile, replace @make rustdoc for $(Q)$(MAKE) rustdoc.
 - Don't do LLVM=1 for all rustdoc generation within `make htmldocs`.
 - Add spaces on definition of RUSTDOC_OUTPUT, for consistency.
